WILLIAM r'. RUST, or PITTSBURGH, PENNSYLVANIA, A'ssIGNoR To THE KOPPERS COMPANY, or PITTSBURGH, PENNSYLVANIA, A conPonATIoN .or PENNsYL- vANIA.

To all whom z't may concern# Be it known that I, WILLIAM F. RUST, a citizen of the United States, residingv in Pittsbur h, State ofgPennsylvania, have Invented a new and useful Improvement in Coke-Handling Apparatus, of which the following is a specification.

This invention relates generally to'mechanism for handling coke discharged from coke-ovens and has for its,essential object the provision of means @for efficiently hantioned. Y'

With the above and other objects in view,

the invention consists in ,certain novel ar rangements, constructions and combinations of parts hereinafter described in a preferred form and particularly set forth in the claims at the end of the specification.

In the drawings:

Figure 1 is a sectional elevational view of a coke-oven battery and coke-handling mechanism constructed in accordance with the present improvements;

Fig. 2 is a plan view of the same.

In the illustrative embodiment of the invention, the ,improved coke-handling mechanism is employed in connection with a cokeoven battery of the by-product type, and,

- for convenience the present description will be confined to this use of the invention. Features of construction of the coke-handling mechanism are .however readily susceptible of other uses, fer example, in connection with coke-oven batteries of the other types; hence, it is manifest that the scope of the invention is by no means confined to the specific use and specific embodimentherein described.

Referring to the drawings, y

There is shown in dotted lines in Fig. 1 and in full lines in Fig.l 2, a coke-oven battery 11, said battery Lvbeing, in the present instance, of the by-product type and embodying in its construction a plurality of cokingchambers or ovens arranged side by side and having the usual alternating heating walls having 1flame lues intermediate adjacent cokingA chambers.

each coking chamber or oven are closed by' the usual doors, indicated diagrammaticalllyT at 1 2 inF ig. 1 and Vwhenf a charge within one of the coking chambers has ybeen coked the door of such chamber is opened or removed, and the hot coke is pushed out. of the chamber into a quenching-car.y 13.

The .quenching-car 13 runs on a track 14 eirtending lengthwise in front of thev cokel side of the oven battery 11, whereby said quenching-car may be moved to positionfor receiving coke discharged from any one of the., series of coking chambers which are located in a row lengthwise' of said battery.

In accordance with the usual practice, the

quenching-car is propelled along its track 14 by-means ofan electric locomotive 15, and when thesaid car has received a' charge of hot coke from one of the aforesaidV coking chambers,it is run to the usual-quenchingstation, not shown, where the hot mass of freshly discharged coke in the car is iooded with cold water to quench the fire and rapidly cool the coke.

Thence, the quenching-car carries the cooled charge of coke along the track 14 to the preferably downwardly inclined cokei wharf or chute 16, the latter being preferably locatedinfront of the oven battery 11, as slown, and along the track 14. The coke is dumped from the quenching-car 1 3 ontov said coke-wharf 16 and, sliding down the latter, discharges onto a belt conveyer' 17 of any approved construction which carries the coke from the wharf-to the usual screening station, not shown. The quenching-car serves a large number of coking chambers in a battery of ordinary construction and as it is quite essential that the coke from eacn chamber be-quenched immediately after it is discharged and furthermore, as the car musth dump its charge of quenched coke before it can receive a fresh charge of coke for quenching, an important requirementr for efficient operation, and in order to save loss of coke, is that provision be made for handling the coke as rapidly as it is dumped from the quenching-car. Y

Ordinarily the coke is carried to the screening station-by the conveyer 17 as rapidly as it is deposited upon the coke-wharf by the quenching-car.

lem presenting serious diiiculties, inasmuch as the coke-wharf is necessarily of somewhat restricted capacity so that it would quickly become illed with coke, and, for reasons mentioned above, the quenching-car must discharge its coke as soon as the same is quenched, or as soon thereafter as practicable, in order to receive a fresh charge of It will be understood that the coke is pushed from the coking chambers of a coke-oven battery systematically and in regular timed sequence.

The present invention obviates the above mentioned problem of coke handling, in the event of a breakdown of the conveyer 17, and provides a means for eiiciently handling the coke until the conveyer can be repaired, which handling of the coke is effected without waste and without any interruption whatsoever in the normal operation of discharging the coke from the coking chambers of the coke-oven battery. Located adjacent to the coke-oven battery 11 and preferably extending lengthwise of said battery and along the track 14 of the quenching-car is a coke storage pit or receptacle 18.

AThis pit 18 may be sunk from the ground level in front of the coke-oven battery 11 and is preferably of multiple-oven capacity, z'. e., of a capacity for receiving charges of coke from a number of the coking chambers or ovens of the aforesaid battery 11 so that coke may be dumped by the quenching-car 13 into the pit .18 for a period of several hours, if necessary, after a break-down of the conveyer 17. The coke may be discharged by the quenching-car 13, after the quenching operation has been effected, into said pit 18 and may be reclaimed therefrom by any suitable instrumentality.v For example, a locomotive crane 19 may run on a track 20, the latter also preferably extending lengthwise of the coke-oven battery 11 and in front of the pit 18, as shown more particularly in Fig. 2, which crane is provided' with a grab bucket 21 of any approved'construction, whereby the coke may be reclaimed from the pit 18. The grab bucket- 21 will be lowered into the pit` 18 to receive a charge of coke and willdeposit suchcharge of coke into a hopper 22. The hopper 22 is provided with a feed spout 23 through which the coke may discharge onto a belt conveyer 24. Preferably, said belt conveyer 24 eX- tends along the side of the it 18 between the latter and the track an is long enough to carry the coke from the hopper 22 to a feed spout 25 which discharges onto the aforesaid conveyeri17 for carrying the coke to the screening station. If desired, the hopper 22 may be mounted on af-"movable support whereby it may be picked up by the locomotive-crane 19 and placed in the most convenient'location along the pit. The coke discharged from the quenching-car will of course not be conveyed to the belt conveyer 17 unless the latter has been restored to good running order and the pit will be of suiiicient capacity-to receive all of the coke discharged from the quenching-car in a normal oven operation of several hours duration.

If desired the coke may be loaded by the grab bucket directly from the pit 18 into railroad cars which can be run along on tracks to any convenient point near the locomotive crane. A further advantage resulting from thel provision of the pit 18 'lies i in the fact that special coke may be dis' charged into it, Whereas coke of ordinary quality will be discharged onto the cokewharf in the usual manner. coke may be conveyed to the screening station separately from the ordinary coke as de- The special' sired and loaded into special cars. lOr, for V a coke-Wharf positioned adjacent to said.
